[APML] OT: M20 Halpha Widefield

["Richard Crisp" <rdcrisp@earthlink.net>]

Fremont Peak was near-perfect on Friday night. It was warm, dry, clear, dark 
and with rock solid seeing. I can't remember when I've seen it like that 
exactly but it's only been a few times.

Here is an image I took on Friday night. It is the Halpha channel of a 
planned tricolor eline image. I took 1.5 hours of Halpha (6x15 minutes) and 
another 1.5 hours of [OIII] which I have not yet processed.

Since I was unable to complete the data acquisition for the object on Friday 
night, I sort of wish I'd just stuck with gathering more Halpha for more 
depth and definition in this image, but I have to work with the data I have, 
not the data I wish I had (apologies to Don Rumsfeld).
